CASH REGISTER AND lNDICATOR.

SPECIFICATION forming part of Letters Patent No. 469,544, dated February23, 1892.

Application filed October 17, 1891- Serial No. 4 (No model.)

To aZZ whom it may concern.-

Be it known that I, HUGO COOK, a citizen of the United States, residingat Dayton, in the county of Montgomery and State of Ohio, have inventedcertain new and useful Improvements in Cash Registers and Indicators, ofwhich the following is a description.

Heretofore in the machines of this character with which I am familiarthe indicator has always had a reciprocating movement, (either in astraightline or in the arc of acircle,) being moved in one directionfrom zero or normal position to make the indication, and then in theopposite direction back to zero or normal position to destroy theindication. Likewise the registering-wheel, while revolving in onedirection only, has been actuated by a device having a reciprocatingmovement, the wheel moving with the actuating device in one direction,but remaining stationary while the actuating device moved in theopposite direction.

My present invention is believed to involve a radically new mode ofoperation in this class of machines, first, by reason of the fact thatthe indicator does not have a reciprocating movement, but revolves inone direction, both to make the indication and to destroy it proparatoryto the next indication, and, second, by reason of the fact that thedriver or actuating device for both the indicator and register is alsorevoluble and has no reciprocating movement.

My invention contemplates the employment of the revolubleindicator andrevoluble driver without the register, and likewise the revolubleregister and revoluble driver without the indicator, as well as theemployment of both the indicator and register with the driver. Thedriver has a uniform stroke or limit of movement (preferably onecomplete revolution) at each operation of the machine, while themovements of the indicator and register vary according to the amounts tobe indicated and registered. A suitable latch or other connecting anddisconnecting device is employed to connect the driver with and permitit to be disconnected from the indicator and register. Where both anindicator and a register are employed in the machine a single latch maybe made to co-operate with both thcindicator and the register. In itsco-operthe fixed stop andthe movable stops, depending upon theconstruction and arrangements of parts employed, for in some instances,as will be explained, the fixed stop or stops may be dispensed with, sofar as the co-operation of the latch with the indicator is concerned,and the latch be arranged to connectthe driver and indicatorindependently of any stopsand the movable stop or stops be aloneemployed to disconnect them. Since the indicator and register are bothrevoluble, the primary device with which the latch connects the driverand to which the latter transmits power is also revoluble. In themachines illustrated in the drawings it is a wheel mounted upon the sameshaft as the revoluble driver. Such wheel may be itself the indicator orregister or be simply the driving gear or wheel for an indicator andregister.

In the simplest form of my invention the driver is connected by thelatch directly with awheel which is itself the indicator, and also witha wheel which is itself the primary registering-wheel, and I have soillustrated the invention in the drawings; but in the full developmentof my invention in complete machines for the market it will often bedesirable to employ the primary revoluble part of wheel, with which thedriver is connected by the latch, simply as the actuator for theindicator or register, which maybe geared or connected with it directlyor indirectly in any suitable manner.

I have devised several different forms of apparatus all embodying thenew mode of operation, and I have no doubt that I will be able to devisemany other forms and that others will be able to do so when the mode ofoperation is explained to them by the following descrip tion of theinvention.

Inasmuch as myinvention is believed to be radically new in principle andmode of operation, it is not restricted in its broader scope to anyparticular construction or arrangement of apparatus, but contemplatesall forms of apparatus involving the new mode of operation,howeverwidely they may differ in construction'.

In the accompanying drawings I have illustrated only a few of thedifferent forms of apparatus which I have already devised, havingselected those which I believe will best facilitate an explanation ofthe invention.

Figure 1 is a side elevation of one form of apparatus with the casing incentral section. Fig. 2 is a horizontal section of the same on the line2 2 of Fig. 1 with a small portion of the top of the casing left to showthe reading opening. Fig. 3 is' a central sectional view of a modifiedconstruction. Fig. 4 is a sectional plan view of the same on the line 44 of Fig. 3 with a portion of the indicator-wheel broken away to exposethe latch-bar beneath. Fig. 5 is a side elevation of anothermodification Fig. 6 is a sectional plan view of the same on the line tobe indicated and registered.

with the casing in central section.

6 6 of Fig. 5.

The same letters of reference are used to indicate corresponding partsin all the figures.

In the views shown in Figs. 1 and 2, A is a revoluble shaft or spindlesuitably journaled in the casing. Loosely mounted upon this shaft,between collars fast thereon, is a wheel B, having a'series ofequidistant notches in its periphery, in this instance thirty. Beneaththe wheel'B, andalso loosely mounted upon the shaft A, is a larger wheel0, which in this instance bears the indicating-numbers upon its upperface and constitutes the indicator. Immediately beneath the wheel Candrevoluble with it is a latch-bar D. The hole at the middle of this bar,through which the shaft A passes, is elongated, as shown by dotted linesin Fig. 2, so that the bar is capable of slight reciprocating movementdiametriwhy ofthe wheel 0. Two lugs E E upon the upper side of the bar,upon opposite sides of the shaft A, extend up through slots in the wheel0 into position to alternately engage the notches in the wheel 13.

Beneath the latch-bar D and fast upon the shaftA is a disk F, which inthis instance constitutes what I call the driver. A plan view of it isshown in dotted lines in Fig. 2, where it will be seen that the oppositehalves of the disk are of unequal radius, each, however, being a truehalf-circle. This unequal size of the two halves of the disk forms twoshoulders at a, diametrically opposite each other on the periphery ofthe disk, and both facing in the same direction. A notch 17 is cut. intothe disk at the base of the shoulder a. The latch-bar D has upon itsunder side, upon opposite sides of the central shaft A, two lugs c c,which co-operate with the shoulder a and notch b of the disk or driver Fin a manner to be presently explained. The opposite ends dd of thelatch-bar D are beveled on substantially-parallel lines and co-opcratewith a series of movable stops or keys G. Upon theunder side of the barD, one near each end, are two lugs or cam-surfaces e e, which co-operatewith a fixed stop or pin II in the manner hereinafter described.

A handle I, fast upon the upper end of the shaft A, may be used to turnthe latter and with it the driver F, which is fast upon the shaft.

There are two series of indicating-numbers upon the upper face of thewheel 0 near its periphery, each set occupying one-third of the circleand separated, upon opposite sides of the wheel, by spaces, each equalto onesix'th of the circle. At some suitable point immediately above therows of numbers the casing is provided with an opening, as at J, throughwhich the numbers upon the wheel may be separately exposed.

The stops G consist of short pins arranged in suitable guides on thecasing and bearing upon their upper ends push-buttons provided withnumbers corresponding with the amounts (See Fig. 5.) In Fig. 2 onlycross-sections of the stems are shown to indicate the relative positionsof the keys and facilitate an explanation of the operation of the parts.In normal position that is, before they are pushed inward-the lower endsof these keys are above the horizontal plane of the latch-bar D; butwhen any key is pushed inward to its full limit its lower end is broughtinto the path of travel of the outer beveled ends of said bar.

Instead of aseries of stops or keys G, mounted in guides and arranged tobe pressed in and moved out, there might be simply a series of holes anda single pin which could be inserted in one hole or another, accordingto the amount to be indicated. This pin might be either wholly detachedfrom the machine or be carried by the outer end of an arm hung upon thecentral shaft A and arranged to beswung over the row of holes, so thatthe pin could be pushed down into any one of them.

Such a movable'pin in connection with a series of holes for itsreception, being afamiliar substitute in this art for a series of keysmounted in dilferent positions corresponding to the holes, the operationof the machine under either arrangement will be readily understood.

In operating the machine to make an indication and registration the keycorresponding to the amount of the sale is pushed inward and the handleI then given a complete revolution. The action of the several partsunder such an operation may be now described in detail.

In the view shown in the drawings the driver F is in its normal positionof rest and the figure 2 is exposed at the reading-opening in indicationof the preceding sale. As

the driver is now revolved in the direction of the arrow its shoulder acomes in contact with timing 0 upon the barD and the driver picks up thebar and indicator-wheel C (which revolves with the bar) and carries themaround with it, the bringing of the notch b in line with the lug cpermitting the bar to move slightly inward as its end (1 clears the keyagainst which it was resting. Just as the driver completes ahalf-revolution the zero at f (l have indicated the zeros of the twosets of numbers as f and f) is brought beneath the reading-opening J.The cam-lug 6 upon the under side of the bar D,near its end (I, at thismoment engages the stationary pin H. As the driver carries the bar onaround the lug e rides over the pin H and the bar is forced to theright, (the elongated hole at the middle of the bar permitting suchmovement, as before explained,) and the lug c on the bar is therebydrawn into the notch Z) in the driver. As the driver continues torevolve the bar D and the indicator-wheel O are moved forward with it,the zero f being carried beyond the reading-opening J and the numbersfollowing it passing successively under'the opening until the beveledend (Z of the bar, which is now traveling below the row of keys, strikesthe key which has been pressed in, whereupon the bar is forced in theopposite direction to that in which it was drawn by the pin H, and thelug c is carried out of the notch Z) in the driver and out of the pathof the shoulder a, and the lug c at the opposite side moved up againstthe periphery of the driver, (as the lug c is against it in Fig. 2.)This positively arrests the bar D, for the end (i of the bar cannotclear the operated key without the bar moving farther in the samedirection, and this it cannot do because of the contact of the lug cwith the periphery of the driver. The bar D and indicator-wheel O arethus arrested at the proper point for the number on the latter whichcorresponds to the value of the operated key to be exposed at thereadingopening, while the driver F moves on to normal position alone.Supposing the operated key to have been 5, the bar D will be leftopposite the 5-key, just as it was left opposite the 2 -key by theprevious operation, and when the driver F is again revolved to make anew indication the shoulder a, when it arrives opposite the 5-key, willengage the lug c, which now stands opposite the 5-key. The lug 0 canthen move into the notch?) as the end of the bar clears the key, and thebar and indicator-wheel will be picked up by the driver and carriedaround byit until the zero f on the wheel is exposed at thereading-opening J, at which time the cam-lug e on the bar D will engagethe pin H and the bar will be forced to the right, in the manner beforeexplained, drawing the lug c farther into the notch Z). As the drivermoves on in the last half of its revolution the indicator-wheel will becarried on around with it until the beveled end of d of the bar D, whichend is now traveling under the row of keys, strikes the key which hasbeen pressed in, whereupon the lug c is disengaged from the notch I) andshoulder a of the driver, the indicator-wheel comes to restdicator-wheel is always left with a number I (in one or the other set)corresponding to the operated key exposed at the reading-opening; thatat the next operation of the machine the driver, during the first halfof its revolution, picks up the indicator-wheel and carries it with ituntil the zero of the other set of numhers is brought beneath thereading opening, and that during the second half of the revolution ofthe driver the wheel is moved forward from this zero until the numbercorresponding to the operated key is brought beneath thereading-opening, whereupon the wheel becomes disconnected from thedriver and stops and the driver goes on to normal position. Thus thedriver makes a complete revolution at each operation, the first half ofwhich revolution is utilized for turning the indicator-wheel to zero andthe second half for turning it forward from zero to make the newindication.

So far I have described simply the indicating mechanism. I will nowdescribe the registering mechanism shown in Figs. 1 and 2. In theconstruction there illustrated the wheel 13 may itself be the primaryregistering-wheel, or it may be simply a driving-gear for any suitabletrain of wheels. In the drawings I have shown it as the onlyregistering-wheel, since this part of the machine may be sufficientlydescribed without illustrating any other wheels for that purpose. Theregistering-wheel B is coupled to and uncoupled from the indicator-wheelC and bar D by the lugs E E, which, as before stated, extend up throughslots in the wheel 0 and alternately engage the notches in the peripheryof the wheel B. In the position of the parts shown in Fig. 2 of thedrawings it will be seen that both of the lugs are free from the wheel.13, so that during the first half of the revolution of the driver, whileit is picking up the indicator-wheel and turning it on to zero, thewheel B remains stationary. When, however, the driver has completed thefirst half of its revolution and brought the indicatorwheel 0 to zero,the movement of the bar D to the right as the cam e rides over the pinH, in the manner heretofore explained, will draw the lug E into one ofthe notches in the wheel B and move the opposite lug E into the extremeouter end of its slot in the wheel 0. From that point forward to thepoint at which the driver and indicator-wheel are disconnected by thebeveled end (Z of the bar D striking the operated key, as beforeexplained, the wheel 13 is turned with the driver and indicator-wheel.When the end of the bar D strikes said key and the bar is forced awayfrom the key, carrying the lug 0' out of the notch b and beyond theshoulder a, as before explained, the lug E is likewise IIO disengagedfrom the wheel B, and the latter is arrested with the indicator-wheeland bar D, and the driver goes on to normal position alone. This lastmovement of the bar D carries the lug E toward the wheel B again andbrings it into the same position relatively to the periphery of saidWheel that the lug E occupies in Fig. 2 of the drawings. At the nextoperation of the machine the lugs E and E, being both free from thewheel B, the latter is not moved until after the driver has completedthe first half of its revolution and brought the indicator-wheel tozero, where-- upon the forcing of the bar D to the right by the passageof the cam 6 over the pin H will draw the lug E into engagement with anotch in the wheel 13, whereupon said wheel will move forward with thedriver and indicatorwheel until the end d of the bar D strikes the key,which has been pressed in, whereupon the driver will bedisconnected fromthe bar D and the wheels B and 0 come to rest.

It will be understood from the above de scription of the parts that whenthe bar D is forced to the right by the pin H, just as theindicator-Wheel is brought to zero, the lug E or E, which happens atthat time to be upon the right side of the wheel B, is moved into theextreme outer end of its slot in the wheel 0, while the lug which is atthat time upon the left side of the wheel 13 is drawn into one of thenotches of said wheel. When the driver is disconnected from theindicator and registering-wheel by the engagement of the bar D with theoperated key, as before explained, the lug E or E, which has beenengaged with a notch in the wheel B, is not only moved out of saidnotch, but also away-from the periphery of the wheel to the position ofthe lug E in Fig. 2, the opposite lug being brought to the position ofthe lug E in said figure, ready to engage a notch in the wheel B at thenext operation of the machine. It will thus be seen that during thefirst half of its revolution the driver does not move theregistering-wheel, but simply turns the indicator-wheel to zero, thatwhen the indicator has been turned to zero the driver becomes locked tothe registering wheel and then turns it forward with the indicator-wheeluntil the proper number upon the latter is brought to thereading-opening, whereupon the driver is disconnected from both wheels.The registering-wheel therefore moves with the indicator-wheel duringthe entire indicating movement of the latter, and thereby registers thevalue of the operated key, While the indicator-wheel has an additionalmovement in being brought to zero, during which movement theregistering-wheel remains at rest. It will also appear from the abovedescription that the stationary pin 11 and cams e and c servenonecessary purpose in connecting the driver with the indicator, forthat is effected by the engagement of the shoulder a with the lug c orc, which stands in its path at the beginning of its movement. The soleing, as seen in Fig. 3.

function of the pin H and cams e and e is to force the bar D to theright when the driver has completed a half-revolution and brought theindicator to zero, and thereby draw the lug E or E into the notch of theregisteringwheel to connect the latter with the driver. In the absenceof the registering-wheel, therefore, the fixed pin I-I, cams e and e,and lugs E and E might be dispensed'with, the remaining parts, essentialto the operation of the indicator, being simply the driver, the

. latch-bar having the lug c o and beveled ends, the indicator-wheelturning with the latchbar, and either the series of stops G or a singlemovable stop in the place of the series.

, Again, I have not shown any means for either positively retaining theoperated key in its depressed position or for returning it to normalposition when another key is operated; but such devices are so common inthis art that it is not thought necessary to illustrate them in detail.

A suitable and common method of accomplishing the desired result wouldbe tosurround each key with a coiled spring, tending to hold it in itsouter position and to provide a spring-pressed detent-plate toco-operate with notches in the stems of the keys, the arrangement beingsuch that when any key was pressed in it would be caught and held by thedetent-pl'ate until a second key. was pressedin, whereupon thedetentplate would be moved by the second key and l the first key bethereby released and then thrown out to normal position by its spring.

In Figs. 3 and 4 I have illustrated a differ- I cut embodiment of myinvention, in which the revoluble driver and indicator-wheel areconnected at different points by means of the dilferent stops or keysand are disconnected at a fixed point. ;shown the general shape of themachine is In the construction there the same as in Figs. 1 and 2, andthe central revoluble shaftA and handle Iare employed. Loosely mountedupon the shaft A is the indicator-wheel K. Fast upon the under side ofthe wheel K is a toothed wheel L, while loose upon the shaft A beneaththe wheel L, 1 separated from it in this instance by a spacing-disk, isa similar notched wheel M, whose notches coincide with those in thewheel L.

, Fast upon the shaft A, beneath the wheel M. is a radially-extendingarm N, which carries upon its upper side in a suitable guideway aradially-sliding latch bar or plate 0, and constitutes the driver of themachine in this instance. Upon the upper side of the latchplate O,nearits middle, is a lug or projection P, which co-operates with two lugs QQ, secured upon the under side of the indicatorwheel K, and upon theupper side of the plate 0 at its outer end is a cam-lug R, whichcooperates with a fixed cam or pin S, depending from the. under side ofthe top of the cas- The outer end of the latch-plate O is beveled offand co operates with a pin or cam S, diametrically opposite the pin S,and with the series of movable IIO stops or keys G. At its inner end theplate 0 is provided with an upwardly-projccting lug or tooth T, whichco-operates with both of the wheels L and M, all in the manner hereinafter explained.

In the construction shown in Figs. 3 and e nineteen keys are shown, andthe indicatorwheel is provided with two series of nineteen numbers, eachrepresenting multiples of five from 5 to 95, with a zero between the 95and 5.

As in the construction shown in Figs. 1 and 2, so in the constructionshown in Figs. 3 and 4:, a full operation of the machine consists inpressing in a key and turning the operatinghandle one completerevolution. This will register the value of the key and leave a numberupon the wheel K corresponding to such value exposed at thereading-opening at J.

In the position of the parts shown in Fig. 4.- the operating-handle anddriver are at rest, the latch-plate O has been slid to its outermostposition, and its tooth T withdrawn from engagement with the wheels Land M by the cam-lug R, riding over the fixed cam S. The number 25 isexposed at the reading-opening in indication of the preceding sale. Itwill be seen that the lug Q on the indicator-wheel K lies directly inthe path of travel of the lug P on the latch-plate 0 when the latter isin its outer position, as shown in Fig. l. The result of this is thatwhen the driver N is revolved by turning the handle I and shaft A thelug P will engage the lug Q and pick up the wheel K and carry it aroundwith the driver. Just as the driver N completes the first half of itsrevolution and brings one of the zeros on the indicator-wheel beneaththe reading-opening the outer beveled end of the latch-plate O strikesthe stationary cam or pin S and is driven slightly inward, far enough tocarry its lug P out of line with the lug Q, with which it has beenengaged, and to thereby disconnect the driver from the illdicator-wheelK, but not far enough to engage the tooth T with the wheels L and M. Asthe driver is turned on in the second half of its revolution the wheel Kremains stationary, with zero exposed at the readingopening, until theouter end of the plate 0, which is traveling beneath the row of keys G,strikes the key which has been pressed in, whereupon said plate is slidstill farther inward and its tooth T enters two coincident notches inthe wheels L and M. From that point on until it completes its revolutionthe driver carries with it both of the wheels L and M. From that pointon until it completes its revolution the driver carries with it both ofthe wheels L and M and also the indicator-wheel K, which is fast to thewheel L. As the driver completes its revolution the cam-lug R on theplate 0 rides over the stationary pin S. The plateis slid to the leftinto its outermost position, withdrawing its tooth T from the wheels Land M, whereupon the latter come to rest with a number upon the wheel Kcorresponding to the value of the Operated key exposed at thereading-opening. Thus when the driver is connected with the wheels atany given key it will turn them just far enough before it isdisconnected from them at the pin S to expose at the reading opening anumber corresponding to the value of the operated key and to add suchValue upon the registering wheel. The outward movement of the plate 0 atthe pin S again brings the lug P into line with the lugs Q and Q on theimlicator-wheel, ready to pick up the latter and carry it around to zeroat the next operation of the machine. The wheel M in this case will bethe registering-wheel or the driver for a train of registering-wheels,as desired. It will be understood from the above description that thetooth T of the latch-plate O engages the wheel M simultaneously with thewheel L and that the tooth is disengaged from both wheels at the sametime. The wheel M thus turns with the wheels L and K while the latterare moving forward from zero to make the new indication, but remainsstationary while the indicator-wheel is being turned to zero during thefirst half of the revolution of the driver.

As in the construction first described, Figs. 1 and 2, any suitabledevices may be employed for temporarily holding the operated key in itsinward position and for releasing it and restoring it to normal positionwhen another key is pressed in. Likewise both in this and thefirst-described construction any suitable device may be employed toarrest the operating-handle and driver when they complete a revolutionand arrive at normal position; but such devices are so common in thisclass of machines that it is unnecessary to illustrate or describe them.

In the construction shown in Figs. and 4 it will be understood that thesole purpose of the lug P on the latch-plate O, the lugs Q Q on theindicator-wheel K, and the fixed cam S is to cause the driver to turnthe indicator to Zero during its first half of its revolution, and toleave it there until again connected with it by the operated key. In theabsence of the indicator-wheel, therefore, these parts might bedispensed with, the only elements essential to the operation of theregister he'- ing the driver N, latclrplate 0, having the cam R, thefixed pin S, keys G, and wheel M. Under the operation of theselast-named parts the driver would move forward from normal positionalone until the outer end of the plate 0 engaged the operated key,whereupon the driver would become locked to the wheel M and turn it onwith it until disconnected from it by the engagement of the lug R withthe pin S.

In Figs. 5 and (3 is represented a third construction embodying myinvention. There the same central shaft A and operating-handle I areemployed. The upper toothed wheel U, loosely mounted upon the shaft A,is the registering-wheel or driver fora train of registering wheels.Beneath this wheel is a sliding latch-bar V, extending diametricallyacross the machine and having an elongated opening at its middle,through which the shaft A passes, which opening permits a longitudinalreciprocating movement of the bar.

Beneath the bar V, the bar resting upon it in this instance, is theindicator-wheel W, loosely mounted upon the shaft A, while beneath thewheel W and fast upon the base X of the machine is a toothedlocking-disk Y, Fig. 5, to be presently described. Upon the upper sideof the bar V at opposite sides of the wheelU and adjacent to itsperiphery are two lugs Z Z, by which the baris intermittently locked tothe wheel U. Upon the under side of the bar V are two lugs A A whichextend down through slots in the indicator-wheel W, so that while thebarV can have a reciprocating movement upon the wheel W the latter andthe barrevolve together. The lugs A A may be either directly in linebelow the lugs Z Z and integral with the latter, if desired, or may beout of line with them, as shown in the drawings, according as thediameter of the lockingdisk Y is less than or the same as the diameterof thewheel U, as willbe hereinafter explained. Secured upon the upperside of the bar V near its outer ends are two lugs DD whose inner facesare beveled or inclined upon substantially parallel lines. Adjacent tothese lugs are pivoted two rocking plates F and F Each of these plateshas upon its upper side a lug H, projecting above the body of the plateand above the upper surface of the adjacent lug Dor D (See Fig. 5.) Theinner faces of these lugs H'are beveled on lines intersecting the linesof the beveled faces of the lugs D D as shown. In the same horizontalplane as the beveled face of the adjacent lug D or D each of the platesF F is provided with an inwardly-projecting shoulder H These shoulders Hand the beveled lugs D D co-operate with the driver, to be described,while the lugs H co-operate with a fixed pin 0 and the series of movablepins or keys G. Springs I, interposed between the lugs D D and theplates F Fiyieldingly hold the latter in the position shown in Fig. 6.The driver consists of a radial arm J, fast upon the shaft A, and havingits outer end extended into position to engage and bear laterallyagainst the beveled lugs D D and shoulder H Under thisconstruction ofthe machine, as well as in those previously described, a full operationconsists in pressing in a keyand giving the operating handle and drivera complete revolution. In the position of the parts shown in Fig. 6 thedriver J is in its normal positions of rest: Thelug H of the plate F atthe right-hand end of the bar V is engaged with the 5-key, and thenumber 5 upon the indicator-wheel W is exposed at the reading-opening inindication of the preceding sale. The lug Z is engaged with a notch inthe wheel U, and the lug A upon the under side of the bar V is engagedwith a notch in the fixed locking-disk Y, Fig.

5, so that the indicator and registering wheels are positivelylockedfrom movement. It will be understood that when a second key is pressedin, preparatory to the next operation of the machine, the last-operatedkey, with which the lug H on the plate F is engaged, (in this instancethe 5-key,) will be released and spring outward to normal position, outof the path of travel of the lug I-I, some suitable devices, such as Ihave before referred to,being employed to accomplish this result. Whenthe handleI is then turned forward in the direction of the arrow, theouter end of the driver, when it reaches the lug D, as indicated by thedotted lines in Fig. 5, bears against the beveled face of the latter andforces the lug, and consequently the bar V, to the left until it passesthe lug. This movement of the bar V to the left withdraws the lug Z fromengagement with the wheel U, thereby disconnecting said wheel from thebar V and wheel W, and also withdraws the lug A from engagement with thelocking-disk Y, and thereby unlocks both wheels and the bar V, so thatthey are all free to move forward. As the driver now continues itsrevolution its outer end engages the shoulder H" of the plate F, andcarries the bar Vand indicator-wheel forward with it, theregistering-wheel U remaining stationary. When the lug H of the plate Freaches the fixed pin. 0, the indicator-wheel has been brought to zero,and the zero h is exposed at the reading-opening. At this point as thelug II rides over the pin 0 the pressure of the end of the driveragainst the shoulder H prevents the plate F from yielding on its pivotand holds it firmly in position with the point of the lug II against theback of the fixed lug D. The passage of the lug H by the pin 0 thereforedraws the barVtoward that side of the machine, and pulls the lug Z onsaid bar into a notch upon the opposite side of the wheel U, therebycoupling the registering-wheel to the bar V and indicator-wheel. Thesliding movement of the bar, caused by the passage of the lug H over thepin 0, has not been sufficient, however, to engage the lug A with anotch in the locking-disk Y, nor to withdraw the shoulder H of the plateF from engagement with the outer end of the driver, and as the lattermoves on forward in the second half of its revolution the indicator andregistering wheel are both carried with it, the numbers which follow thezero It upon the indicator-wheel passing successively under thereading-opening J. When the lug H of the plateF reaches the key whichhas been pressed in, its beveled face engages such key, and as the lineof the 'keys is farther from the center of the machine than was the pin0 the bar V is forced still farther to the right as the lug rides overthe key. This movement of the bar is sufficient to disengage theshoulder H from the end of the driver before the lug H quite clears thekey, and also draws the lug Z on the opposite side of the wheel Ufarther into the notch in said wheel with which it was engaged as thelug 11 passed the pin 0, as before described, and brings the lug A uponthe under side of the bar V into one of the notches in the fixedlocking-disk Y, thereby positively arresting and locking both theregistering and indicator wheels, (with the proper number on the latterexposed at the reading-opening,) while the driver is freed from both andmoves on to normal position alone.

At the next operation of the machine, when a new key is pressed in, thekey with which thclug H of the plate F hasjust been engaged is releasedand springs out to normal position. When the operating handle and driverare then turned forward, the outer end of the driver first engages thebeveled face of the lug H on the plate F which is now on the left sideof the machine, and forces the 7 bar V to the left, thereby withdrawingthe lugs Z and A from engagement with the wheel U and locking-disk Y,respectively, and releasing both the indicator and theregistering-wheel. The driver then engages the shoulder H of the plate Fand picks up the indicator-wheel, carrying it on around with it untilthe zero 7b is brought beneath the reading-opening, at which point inthe operation the lug ll of plate F engages the pin 0 and draws the lugZ on the opposite side of the wheel U into a notch in said wheel. As thedriver continues its movement the indicator and registering-wheel areboth carried with it until the lug ll reaches the key which has beenpressed in, whereupon the driver is disconnected from them and they arearrested and looked, all as before eX- explained in connection with thefirst-described operation.

It will be understood from the above description that during the firsthalf of its revolution the driver unlocks the registeringwheel andindicator and turns the latter to zero; that at the completion of thishalf of the revolution the registeringwheel is coupled to theindicator-wheel and driver, and during the second half of the revolutionmoves forward with them until the operated key is reached, whereupon thedriver is disconnected from both wheels and moves on to normal position.

It will be understood that the sole purpose of the lugs Z and Z upon thebar V and the fixed pin 0 is to connect the driver with theregistering-wheel U, and that in the absence of such wheel the lugswould be dispensed with; also, that the only purpose of the lugs A and Ais to co-operate with the lockingdisk Y. I have before stated thatthoselugs may either bein line with the lugs Z Z above or may be out ofline with them and farther away from the center of the machine. If theyare in line, then the locking-disk Y will have to be of smaller diameterthan the registering-wheel U, since the lugs Z and Z are first to beengaged with the wheel U, while the lugs A A remain disengaged frourthedisk Y, and they are to be drawn farther into the notches in the wheel Uwhen the lugs A A are engaged with the disk Y, as before described.

Thus farl have not explained why the plates F and F are pivoted to thebar V instead of being rigidly secured thereon. The mainpurpose of thisarrangement of the plates 1s to enable the lug H, which is caught on theoperated key, to yield and slip by said key at the beginning of the nextoperation of the machine, in case the same key should be again operated.Thus in Fig. 6 the amount indicated is five, and the lug ll of the plateF is caught upon the 5-key. Now if the neXtsale should be five, thissame 5-key would have to be pressed in or allowed to remain 111. Ineither event if the plate F could not yield the lug H would becomelocked against the key when the handle was started forward and the endof the driver J brought against the beveled lug D to press the bar Vtoward the left, as before described; but with the plates made yielding,as they are, when the end of the driver bears against the lug D the barV can be moved to the left against the stress of the spring I at theopposite end, and as the end of the driver passes the lug D and comes incontact with the shoulder H and begins to turn the bar V forward with itthe lug ll of the plate F slips off the 5-key and the spring I restoresthe plate to normal position. Under the exact construction of the partsshown in Fig. 6 this yielding arrangement of the plates F and F serves,also, another purpose, and that is to enable the plate to yield and itslug H to clear a newlyoperated key at the beginning of the nextoperation of the machine in case such key should be of higher value thanthe last-operated one, and therefore stand in the path of the lug ll atthe beginning of the forward movement of the bar V. Thus with the partsin the position shown in Fig. 6, if the nextoperated key should be the8-key, we will assume that the o-key, with which the lug II has justbeen engaged, will be released and spring out of the path of thelug; butwhen the bar V is forced to the left by the engagement of the driverwith the beveled lug D at the beginning of the forward movement of thedriver the lug II of the plate F will be brought into line with thekeys, and the lower end of the newly-operated S-key will stand directlyin its path. If the plate I could not yield, the lug II would becomelocked against such key, and the machine could not be further operated;but with the plate made yielding as it is the lug slips by the key andthe spring I then resets the plate. The last-described operation is,however, incidental to the particular construction and arrangement ofthe parts shown in Fig. 6, for the beveled lugs D D might be made ofsuch shape that the engagement of the driver with one or the other ofthem at the beginning of its forward movement would force the bar V farenough to theleft to carry the lug H at the opposite endof the barentirely inside of the line of the keys, so that in the forward movementof the barthe outer side of the lug would clear the inner side of thenewly-operated key.

As I have before stated, the wheels 0, K, and V, which bear theindicating-numbers, may, instead of being themselves the indicators, besimply the actuators or drivingwheels for any suitable indicatingmechanism, with which they may be geared or other wise connected in anysuitable manner; nor is itessential that the indicator with which thesewheels may be connected as actuators should have two sets ofindicating-numbers, as have the wheels shown in the drawings, for bygearing any one of these wheels to an indicator by a suitable train ofspeed-increasing gears the indicator need have but one set ofindicating-numbers.

From the foregoing description it will be seen that under all theconstructions illustrated the latch, in connecting the driver with anddisconnecting it from the registeringwheel, c'o-operates with both thefixed stop or stops and the movable stop or stops; but that inconnecting the driverwith and disconnecting it from the indicator-wheelit co-operates with only the movable stop or stops, except in theconstruction shown in Figs. 3 and 4. It will thus be seen that in thecombination of the indicator-wheel and driver my invention is notrestricted to the employment of both a fixed stop or stops and a movablestop or stops, but contemplates the broad combination of the indicatorrevolving in one direction only, the revoluble driver also revolving inone direction only, and any suitable means for connecting anddisconnecting them. It Will also be seen that under all theconstructions illustrated the revoluble part,with which the latchconnects the driver, is in each case a wheel, whether theregisteringwheel, the indicator-wheel, or a driving-wheel for one or theother be considered, so that where my claims refer to a wheel they areintended to incln'de each and all of such revoluble devices connectedwith and disconnected from the driver.

It will be understood that in machines in which a type-wheel is employedto print the dilferent amounts indicated it will be driven by the sameWheel which here drives the indicator, and may be employed either inconnection with or withoutthe indicator and registering wheels.

From the foregoing description it will have been seen that in theconstructions shown in Figs. 1 and 2 and 5 and 6 the driver isdisconnected from the indicator and register at difierent pointsdetermined by the operated key, while in the construction shown in Figs.3 and 4 it is connected to them at different points and disconnectedfrom them ata fixed point. All of these constructions embody the samegeneral combination and mode of operation, and my broader claims aredesigned to cover all of them; but I also desire in this specificationto claim more specifically the construction and mode of operation underwhich the driver is disconnected from the indicator and register at afixed point.

In another pending application, Serial No. 418,252, filed January 16,1892, I have specifically claimed the mode of operation in which thedriver is disconnected from theindicator and register at differentpoints.
